John, I do not know the front to back weight ratio's,,, but my guess would be 52 to 53 % on the front.
Here are the weights for a 53 Coupe
Champion Inline 6 Coupe 2,760
Commander V8 Coupe 3,180 (bigger motor and heavier frame etc,,, same body)
Both the Inline 6 and V8 coupes had the same 120.5" wheelbase..
Hope that helps
Charles
I estimate my 53 Stude in Race trim to weigh 3500 to 3600 (without me) For Maxton, Texas and Loring, I do not see the need to increase the weight,,, I have been told for Bonneville that I need provisions to add and balance more weight...
